To configure as an alias git lol:

Download a McGraw Hill Education eTextbook

Download a McGraw Hill Education eTextbook

If you purchase a textbook from McGraw Hill, the website to view it is clunky and only works on some devices. You can't go to specific page numbers, the search is super slow, etc. That's why I wrote this script to download the textbook as an ePub file for your own viewing.

Using this script is 100% legal. McGraw Hill publicly hosts their ebooks online in order for their web client to download it. Moreover, to use it, you must already have purchased the book you would like to download, so it is legally yours to use as you please. However, it IS illegal to use this for piracy purposes. DO NOT DISTRIBUTE ANY TEXTBOOKS YOU DOWNLOAD USING THIS SCRIPT.

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

# DSA Question Bank
## Arrays, Hashing, Prefix/Suffix
1. Find the second largest element in one pass without extra space.
2. Find the k largest distinct elements without fully sorting the array.
3. Find the two numbers that appear once when every other number appears twice.
4. Find the majority element that appears more than n / 2 times.
5. Find all elements that appear more than n / 3 times.
6. Count inversions in an array.

PostGIS Functions — A Hands-On Reference

A personal cheat-sheet for the core ST_* functions, grouped A–E by what they do. Every query here is runnable and every output shown was produced by actually running it. It uses a tiny self-contained demo dataset (two throwaway tables), so you can paste this whole file into psql and follow along without touching the app's data.

  • A. Constructors — build geometry from numbers or text
  • B. Accessors / Output — read data back out of a geometry
